This handy tool, developed by an engineer at Red Hat, checks your Ironic JSON file for errors such as missing passwords, or non-unique MAC addresses. The script also tests connections to your bare metal (or virtual nodes in my test lab) to ensure that they are accessible.

Or download the script directly via this link.

Usage, at least in my case, is shown below. Here, I am running the script against my instackenv.json file.

[code language=”css”]
# python instackenv-validator.py -f instackenv.json
